Automation Workflow and Hybrid System
• ReleaseRailsAppwithGitlab whenappliedDocker• (CI– CDworkflowwithRailsAppwhenapplyDocker)
• Designauto-scalesystemwithDockeronKubernetesandAWSCloud• ScalablesystemwhenusingonlyAWSCloud• Auto-scalesystemonKubernetesandAWSCloud
Dockerize RailsApps
- Dockerfile- EnvironmentVariables- Gem requirement- Specify Gem with Gemfile and
Gemfile.lock
Gitlab-CI & Gitlab-multi-runner
- Autotest- AutoQ/A- MultipleEnvironmentTesting- AutoReleaseImages- AutodeliveryDockerImagestoDocker-Hub- Autodeployment
CI-CDworkflowwithDocker

Auto-Scaling
• Makethesystemeasierwithscalable• Alltheactionswith automation• Policy scale-up and scale-down
AutoHealing
• Auto define unexpected event of infrastructure• Auto fix
KubernetesArchitecture• Kubernetes isanopen-sourcesystemforautomatingdeployment,scaling,andmanagementofcontainerizedapplications.
• “Writeoncerunforever”
Features focus• Pods• Replication Controller • Services• LBaaS• HPA – Horizontal Pods Autoscaling• Constraint• Label• Namespace• …
HybridsystemArchitecture
• DEV:• MakeITsimple• Easytouse• DocumentsasCode• Notneedtosetup
• OPS• Easytomaintain• Becomehumanops
Disadventage
• Workflow: • Developer must know about system – Devops • Can’t apply docker to all old services• Dockerize old big system is so hard• Personal know-how
YOUR GOAL• Hybrid system with HA, AUTO-HEALING, AUTO-SCALING, AUTO-
DEPLOYMENT…• Easy with “OPS”• Easy with “DEV”
